Component Respond to IQ packet reply

We have defined an AbstractComponent using Whack library 2.0.0 and it works fine for sending and receiving XMPP messages.

However, when we send a IQ GET request to a client of the type:

we get an IQ reply from the XMPP client, however we cannot seem to find a way to receive it within the component and then parse it.

We tried both the handleIQSet & handleIQGet methods with Override, to no effect.

Any ideas?
